The .257 Roberts was designed in the 1920s when wildcatter Ned Roberts started to do experiments on the .257 caliber cartridges. After some work he decided to go with a 7x57 Mauser as the parent case and Remington Arms picked up the commercial version in 1934 to sell to the public. The ballistic performance based off four grain types for velocity are 3,563 ft/s (75 gr), 3,368 ft/s (90 gr), 3,108 ft/s (100 gr), and 2,777 ft/s (115 gr).

The .257 Roberts failed to gain any traction after the initial introduction of the 117 grain round into the market because the .250 Savage was considered to have better velocity. After the introduction of the .243 Winchester the .257 Roberts moved even further back on the market. The factory load 100 grain bullets can produce reasonably fast kills on medium sized game on targets up to 150 yards, but is better suited for medium sized game at 100 yards. The advantage the .257 Roberts gives to hunters is a reduced recoil compared to other rounds for people who have sensitive shoulders that cannot take the higher recoil from other cartridges.

The .257 Roberts factory loads are available on the commercial market inside the U.S. by manufacturers such as Olin, Hornady, and Federal. Hand loading brass has been more effective increasing velocity on rounds and can be purchased from Hornady, Sierra, and Federal. The 120 grain Speer and 100 grain Nosler Partition have been two of the more successful hand loading rounds when it comes to acceptable wound penetration on targets.
